This study investigated on how well the students can explain science concepts through movie scene clips as a summative assessment. It focused on the depth of the concepts learned in physics, chemistry, and earth and life science, and to the 21st century skills developed by the students while combining the scene clips and reviewing the concepts observed from the scenes.  Ninety seven students from three different schools in Luzon, Philippines during the first semester of school year 2017-2018 were selected to participate: grade 12 students under the Science, Technology, Engineering, and Mathematics strand enrolled in General Physics 1 from Pamantasan ng Lungsod ng Maynila, second year college students enrolled in General Chemistry from Bataan Peninsula State University and grade 11 students under the General Academic Strand  enrolled in Earth and Life Science from Isaac Lopez Integrated School in  Mandaluyong City. Students grouped in 4-5 members were required to choose a film and clip the scenes which have applications and violations of science concepts observed from the scenes. The outcomes were then presented in class. The result reveals a 3.1 mean in the students’ mastery of the concepts in physics, 3.0 mean in chemistry, and 3.2 in earth and life science, with 4.0 as the basis of an excellent mark. This shows that the mastery of the concepts learned in each subject falls under the proficient category. The study has also found support in the development of the students’ 21st century skills, which are creativity, teamwork, communication, critical thinking, digital competencies, leadership, and planning.
